| Abstract | Requirement: Users of remoting systems (e.g., RPC and Messaging) want to concentrate on the data being sent. They should not have to use a different programming model just to use a different protocol. Problem: Remoting systems need to support alternate encodings, protocols and transports, either because of evolving standards or through dynamic negotiation with a peer. Solution: This paper has two main ideas. First, it clearly partitions a remoting system into four main blocks: presentation, encoding, protocol and transport. It identifies the extensibility points, the responsibilities and interactions of those blocks. Second, it shows how, for each message arriving on a connection accepted and created by an Acceptor, the Acceptor acts as a factory for specific encoders and protocol handlers. Thus a remoting system can dynamically adapt to new encodings, protocols and transports without changing the programming model presented to the programmer. Experience: We have used this model to adaptively alternate between XML and binary encoding, protocol and transport combinations in an RMI system. We show size and performance results for these combinations. Conclusion: This model isolates change from the remoting system user while allowing common remoting infrastructure to be extended and reused. The model does not degrade performance. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
